Title: Optical disk
Inventor: KATO SEIZO
IPC: G11B7/24047
Filed: 1997-08-05
Abstract: PROBLEM TO BE SOLVED: To make an optical disk compatible with another optical disk and to suppress aberration by specifying the thickness of a clamping area and the thickness of a recording area differently from each other. SOLUTION: The clamping area of a size 35 mm and the thickness 1.2 mm is formed around the through hole of the optical disk, and the recording area of the thickness 0.6 mm is formed on its periphery. At this time, the thickness of the clamping area is made an error of ±0.1 mm extent, and the thickness of the recording area is made the error of ±0.05 mm extent. In such a manner, by making the thickness of the clamping area the same as another optical disk, a chucking device common with another disk is made usable, and by thinning the thickness of the recording area, even when a disk surface is tilted to the optical axis of laser light emitted through an objective lens 18 of an optical pickup, since coma aberration occurring then is proportionated to a value multiplying a numerical aperture NA<3> by the thickness of the disk, the coma aberration is suppressed.

Title: Signal terminating circuit and signal transmitting method therefor
Inventor: AKIYAMA KENJI
IPC: H04L25/02
Filed: 1995-07-28
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption in association with the level transition of a pull-up resistance and a signal, to reduce power consumed by a terminating resistance for impedance matching and to shorten transmission time required pre signal transmission. SOLUTION: When a driver 11 is driven and an input signal (b) is fetched in a signal line (a), the signal level of the signal line (a) is set to the signal level of the input signal (b), and a switch control circuit 19 changes over a first switch element 18a and a second switch element 18b to power lines or ground line by the signal level of the signal line (a). Since current hardly flows in a resistance element 17, power consumption can be reduced. A period when the driver 11 drives the signal line (a) is caused to terminate earlier than that when a receiver reads the signal, and transmission time is shortened.

Abstract: PURPOSE:To reduce the effect of the propagation delay of a dummy sense amplifier output signal by setting the bit potential discriminating level of a dummy sense amplifier in a dummy sense amplifier circuit at a value different from that of the sense amplifier in a main body. CONSTITUTION:When the potential level of a bit line is varied from the inverse of VSS side, the sense level of the dummy sense amplifier is made approach to a VSS side nearer than a main body side by making the capacity of a dummy sense amplifier Nch transistor larger than that of the main body side, and the effect of the propagation delay is reduced by making the inverting time of the dummy sense amplifier faster by the propagation delay share of the signal than that of the main body, preventing a malfunction. When the potential of the bit line approaches from a +VDD side, the same effect can be obtained by making small the capacity of the Nch transistor or making larger that of a Pch transistor.
